IMPROVEMENT IN EXCAVATIG APPARATUS.

The Schedule referred'to in these Letters Patent and making part. of the same.

To all whom fit may concern: n

Be it known that I, PHILO W. CLARK, of Oblong, in the county of Dutchess and' State f New York, have invented a new and useful Improvement in EX- cavat-ing Apparatus; and I do hereby declare that the following is a full, clear, and exact description thereof', which will enable others skilledin the art to make and use the same, reference being had to the accompanying drawings forming part of this specification, in which- Figure 1 is a top or plan view of my improved ex cavatiug apparatus.

Figure 2 is a detail side View of the same, partly in section, to show the construction.

- Similar letters of referclice indicate corresponding parts.

My invention has for its object to furnish an im'- proved excavating apparatus,` designed for use in transierring the soil from the place being excavated, and loading it-upou a cart orthrowing'it down an em'- bankment; and

It consists in the construction and combination of various parts of the apparatus, as hereinafter more fully described.

A represents an ordinary scraper, ot' which c* is the inail, and a2 is the handle.

To the eye of the bail a1 is att-ached one lend of the rope or chain B, which passes through a hole formed in or around a pulley connected with, or pivoted to, a

post, C. The' other endof the rope or chain B is attached to a horse-power or other power.

To the middle part of the rear end of the scraper A, is attached one end of a shortchain, D, the other end of which is attached to the taill end of an ordinary plow, E, or other tool for loosening the soil.

To the forward end of the beam'of the plow E is attached one end of the rope or chain F, which passes around a pulley or through the eye of a hook, hookedv into the chain G.

The other end of lthe rope or chain F, is attached to a horse-power or other suitable power.

The ends of the chain G are attached to two posts H, firmly set in the ground.

By this construction, when the apparatus is drawn in one direction the soil will be loosened by the plow E, and, as it is drawn in the other direction, the soil will be collected in the scraper A and carried olf, the relative positions of said scraper and plow enabling the same man to operate both, as they are alternately used.

The ropes orchains B and F, may be attached to my improved horse-power or any other suitable machine,l and should be so arranged that the draft may The 'posts G and H should be shifted as the exca-` `vating progresses, and the point at which the rope or chain F is connected with the chain G, may b e shifted from point to point along Said chain Gr.v

I is a guide-platform, inclined or not, as the circumstances ot' the case may render advisable, staked or otherwise secured tothe ground at the end ofthe excavation, in such aposit-ion that the full scraper A will be drawn up it.

The sides ofthe platform I project upward, and are so inclined as to guide the loaded scraper into the proper position for dumping.

The forward side of the platform I should be so elevated that a cart may be driven under it to receive the dirt from the scraper.

rlhe forward parto' the platform I may be a little inclined downward, to bring the loaded scraper into a more favorable position for dumping, and should be provided with posts or other suitable stops for the forward end of the loaded scraper to strike against, to

.cause it to dump its load.

1n cases where the soil is so loose as not to require to be loosened, two Scrapers may be connected with each other in such a way that the empty scraper'may be drawn back while the full one is being drawn forward, or two Scrapers and two "plows may be thus connected.

Having thus described my invention,

I claim as new and desire to ksecure by Letters Patent- 1. The combination of a scraper, A, plow E, draftropes B andF, chain G, and stay-posts C and H, with each other, substantially as herein shown and de; scribed, and for the purpose set forth.

2. An apparatus consisting essentially cfa plow, earth-collector, and inclined plane, each arranged with respect to the others, as specilicd, whereby on its forward movement the earth is loosened, while on its return movement it is gathered and carried up to a point where it may be readily dumped into anyreceptacle prepared for it.
